identity server4 在接入时遇到错误：Exception: Correlation failed. Unknown location的解决方法

背景：前面尝试了用https的方式解决，但是需要有域名申请的证书，否则被他保护的api被别人调用时报错(没找到解决方法)

 

尝试：放弃https的方式，还用原来的http的方式，解决Correlation failed. Unknown location的问题，找到这个文章，asp.net core - OIDC correlation failed in Microsoft Teams authentication popup (no problems in browser) - Stack Overflow

 

用下面的代码搞定：

private void CheckSameSite(HttpContext httpContext, CookieOptions options)
{
    if (options.SameSite == SameSiteMode.None)
    {
        var userAgent = httpContext.Request.Headers["User-Agent"].ToString();
        // TODO: Use your User Agent library of choice here.
        if (/* UserAgent doesn’t support new behavior */)
        {
               // For .NET Core < 3.1 set SameSite = (SameSiteMode)(-1)
               options.SameSite = SameSiteMode.Unspecified;
         }
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<CookiePolicyOptions>(options =>
    {
        options.MinimumSameSitePolicy = SameSiteMode.Unspecified;
        options.OnAppendCookie = cookieContext => 
            CheckSameSite(cookieContext.Context, cookieContext.CookieOptions);
        options.OnDeleteCookie = cookieContext => 
            CheckSameSite(cookieContext.Context, cookieContext.CookieOptions);
    });
}

public void Configure(IApplicationBuilder app)
{
    app.UseCookiePolicy(); // Before UseAuthentication or anything else that writes cookies.
    app.UseAuthentication();
    // …
}

 

我的代码记录：

 

public class Startup
    {
        public static IContainer AutofacContainer;
        public Startup(IConfiguration configuration)

                // TODO: Use your User Agent library of choice here.
                //if (/* UserAgent doesn’t support new behavior */)
